Introduction
This document is a type-C standard as stated in ISO 12100.

This document is of relevance, in particular, for the following stakeholder groups representing the

market players with regard to machinery safety:
— machine manufacturers (small, medium and large enterprises);

— health and safety bodies (regulators, accident prevention organisations, market surveillance etc.)

Others can be affected by the level of machinery safety achieved with the means of the document by the

above-mentioned stakeholder groups:
— machine users/employers (small, medium and large enterprises);

— machine users/employees (e.g. trade unions, organizations for people with special needs);

— service providers, e. g. for maintenance (small, medium and large enterprises);

— consumers (in case of machinery intended for use by consumers).

The above-mentioned stakeholder groups have been given the possibility to participate at the drafting

process of this document.

The machinery concerned and the extent to which hazards, hazardous situations or hazardous events

are covered are indicated in the Scope of this document.

When requirements of this type-C standard are different from those which are stated in type-A or

type-B standards, the requirements of this type-C standard take precedence over the requirements of

the other standards for machines that have been designed and built according to the requirements of

this type-C standard.”

Acknowledging that, at the time of publication, the requirements included in this document do not

represent the state of the art, a transition period of 24 months is permitted after the date of publication,

such that manufacturers can develop their products sufficiently to meet the requirements of this

standard.

The purpose of this document is to address the operator's visibility in such a manner that the operator

can see around the slewing rough-terrain variable-reach truck to enable proper, effective and safe

operation that can be quantified in objective engineering terms. This document includes a test method

that uses two lights placed at the location of the operator’s eyes. The maskings due to the truck, its

components and attachments and a standard test load are determined around the truck, starting at a

boundary line 1 m away from the smallest rectangle that encompasses the truck out to the visibility

test circle. The radius of the circle is 12 m. The method used does not capture all of the aspects of

the operator’s visibility but provides information to assist in determining the acceptability of visibility

from the truck. Criteria are included in this document to provide guidance for designers as to the extent

of visibility maskings that are acceptable.

Due to the truck’s capability and the intended operation mode of the truck, the test method is divided

into 4 tests representing the main utilisation:

— driving between 2 work sites, at high speed: visibility is checked in the front sector of the 12m

boundary. Crab steering and 4-wheel steering are not permitted at high speed, so there is no need

to check visibility at the sides of the truck, neither at the rear-side;

— pick-and-carry: manoeuvring and slewing at low speed on work site, with possible crab or 4-wheel

steering, in both forward and backward direction. The risk is then in close proximity of the truck

and visibility is checked at 1 m rectangular boundary all around the truck except for trucks with

an operating mass greater than 20 tons or a maximum lift height above 20 m, where the distance is

greater than 1 m to the front of the truck;

---------------------- Page: 12 ----------------------
SIST EN ISO 18063-2:2021
ISO 18063-2:2021(E)

— pick-and-place: slewing the upper structure at low speed, the truck being on stabilisers (if any) in

static position. The risk is in close proximity of the boom and/or the tail. The test can be performed

in any position of the upper structure, and this document considers the worst case, i.e. when in

forward aligned position. Therefore, visibility is checked at 1 m rectangular boundary except for

trucks with an operating mass greater than 20 tons or a maximum lift height above 20 m, where the

distance is greater than 1 m to the front of the truck;

— on forks: the market is now offering trucks with long reach (up to 40 m and more). Visibility to the

forks is then of high importance to ensure visibility to the overall front size of the truck.

For the eye spacing, adjustments (up to the limits specified in Tables 1 and 2) can be made considering

that the operator has the capability to turn their head and move their body torso side to side. The eye

spacings used are less than the maximum permitted values based on the ergonomics of the operator.

This is done to maintain the current state-of-the-art of trucks.

Standard test loads are carried on devices on the truck during the visibility tests. They are intended

to be dimensionally representative of typical loads carried by slewing rough-terrain variable-reach

trucks and are used to determine their masking effects and to define representative boom geometry of

the truck in normal uses.

The established visibility performance criteria are based on the physical aspects of the human

operators and ground personnel using various representative dimensions and the design of trucks that

have provided acceptable visibility. To establish the visibility criteria, a combination of the eye spacings

and masking widths are used. Multiple maskings in sectors are acceptable where there is adequate

spacing between the individual maskings. Where the direct visibility is considered inadequate,

additional devices for indirect visibility [mirrors or closed-circuit television cameras (CCTV)], can be

used to achieve acceptable visibility. For the rectangular boundary (RB) additional devices for indirect

visibility (mirrors or CCTV) are preferred. Other aids (see ISO 16001) can be used exceptionally.

1 Scope

This document applies to slewing rough-terrain variable-reach trucks (hereinafter referred to as

trucks) as defined in ISO 5053-1:2020, 3.22, that have a specific seated operator’s position, on the left-

hand side of the boom, or centre position (excluding operator position on the right side of the boom).

This document specifies a static test method for determining and evaluating the operator’s visibility

on a rectangular boundary close around the truck and on a 12 m visibility test circle. Performance

requirements for visibility are specified in this document. A calculation method or computer simulation

can also be used.

This document does not provide performance requirements for the additional means for indirect

visibility.
This document also covers information to be provided by the manufacturer.

Introduction
This European Standard is a type-C standard as stated in EN ISO 12100.

The machinery concerned and the extent to which hazards, hazardous situations and events are

covered are indicated in the scope of this standard.

Acknowledging that, at the time of publication, the requirements included in this standard do not

represent the state of the art, a transition period of 24 months is permitted after the date of publication,

such that manufacturers can develop their products sufficiently to meet the requirements of this

standard.

Where there are provisions of this type-C standard which are different from those which are stated in

type A or B standards, the provisions of this type-C standard take precedence over the provisions of

the other standards, but only for machines that have been designed and built in accordance with the

provisions of this type-C standard.

For relationship with EC Directive(s), see informative Annex ZA which is integral part of this document.

According to the CEN/CENELEC Internal Regulations, the national standards organizations of the

following countries are bound to implement this European Standard: Austria, Belgium, Bulgaria,

Cyprus, Czech Republic, Denmark, Estonia, Finland, France, Germany, Greece, Hungary, Iceland, Ireland,

Italy, Latvia, Lithuania, Luxembourg, Malta, Netherlands, Norway, Poland, Portugal, Romania, Slovakia,

Slovenia, Spain, Sweden, Switzerland and the United Kingdom.

The purpose of this standard is to address the operator's visibility in such a manner that the operator

can see around the slewing rough-terrain variable-reach truck to enable proper, effective and safe

operation that can be quantified in objective engineering terms. This standard includes a test method

that uses two lights placed at the location of the operator’s eyes. The maskings due to the truck, its

components and attachments and a standard test load are determined around the truck, starting at a

boundary line 1 m away from the smallest rectangle that encompasses the truck out to the visibility

test circle. The radius of the circle is 12 m. The method used does not capture all of the aspects of

the operator’s visibility, but provides information to assist in determining the acceptability of visibility

from the truck. Criteria are included in this standard to provide guidance for designers as to the extent

of visibility maskings that are acceptable.

Due to the truck capability and the intended operation mode of the truck, the test method is divided

into 4 tests representing the main utilisation:

— driving between 2 work sites, at high speed: visibility is check in the front sector of the 12m

boundary. Crab steering and 4-wheel steering are not permitted at high speed, so there is no need

to check visibility of sides of the truck, neither at the rear-side;

— pick-and-carry: manoeuvring and slewing at low speed on work site, with possible crab or 4-wheel

steering, in both forward and backward direction. The risk is then in close proximity of the truck

and visibility is checked at 1m rectangular boundary all around the truck;

— pick-and-place: slewing the upper structure at low speed, the truck being on stabilisers (if any) in

static position. The risk is in close proximity of the boom and/or the tail. The test could be performed

in any position of the upper structure, and this standard will consider the worst case, i.e. when in

forward aligned position. Therefore, visibility is checked at 1m rectangular boundary;

— on forks: the market is now offering trucks with long reach (up to 40 m and more). Visibility to the

forks is then of high importance to ensure visibility to the overall front size of the machine.

For the eye spacing adjustments (up to the limits specified in Tables 1 and 2) can be made considering

that the operator has the capability to turn the head and move the body torso side to side. The eye

spacings used are less than the maximum permitted values based on the ergonomics of the operator.

This is done to maintain the current state-of-the-art of trucks.

Standard test loads are carried on devices on the truck during the visibility tests. They are intended to

be dimensionally representative of typical loads carried by variable-reach slewing trucks and are used to

determine their masking effects and to define representative boom geometry of the truck in normal uses.

The established visibility performance criteria are based on the physical aspects of the human operators

and ground personnel using various representative dimensions and the design of trucks that have

provided acceptable visibility. To establish the visibility criteria, a combination of the eye spacings and

masking widths are used. Multiple maskings in sectors are acceptable where there is adequate spacing

between the individual maskings. Where the direct visibility is considered inadequate, additional

devices for indirect visibility [mirrors or closed circuit television cameras (CCTV)], can be used to

achieve acceptable visibility. For the rectangular 1 m boundary (RB) additional devices for indirect

visibility (mirrors or CCTV) are preferred. Other aids (see ISO 16001) can be used exceptionally.

methods and their verification:

verification —
Part 2:
Slewing trucks
1 Scope

This standard applies to rough-terrain slewing variable-reach trucks (herein-after referred to as

‘trucks’) as defined in ISO 10896-2 that have a specific seated operator’s position, on the left hand side

of the boom, or centre position (excluding operator position on the right side of the boom).

This standard specifies a static test method for determining and evaluating the operator’s visibility on

a rectangular 1 m boundary close around the slewing rough-terrain variable-reach truck and on a 12 m

visibility test circle. Performance requirements for visibility are specified in this standard.

It applies to trucks for operation on work sites.

7.1 Test-surface marking and truck location on the test surface

7.1.1 Mark a visibility test circle of 12 m radius on the test surface with the two centrelines as shown

in Figure 2. Mark the centre-point of the visibility test circle to enable accurate alignment of the truck

(see 6.3.1).

7.1.2 Mark where the sector A intersects the line of the circle on the test surface as shown in Figure 2.

7.1.3 Position the fork mounted load and adjust the boom and forks as defined in 6.3.2.2.

NOTE RB remains the same for all tests and is measured and set as illustrated in Figure 2 and Figure 3

7.1.4 Mark the test machine boundary (TMB) as the smallest rectangle that can be placed around the

vertical projection of the truck (i.e. chassis + upper structure) and test load as shown in Figure 2.

7.1.5 Mark the rectangular 1 m boundary (RB) on the test surface at a distance of 1 m from the test

machine boundary, as shown in Figure 2.
